前端小纠结--VS Code调试配置分享

这不是一篇科普文，只是一篇浏览器调试配置的分享（主要对准对准vs code调试）

调试配置

使用vs code插件debugger-for-chrome、debugger-for-edge(EdgeHTML&Chromium)和Debugger for Firefox调试之前，会自动在工程下添加.vscode文件夹，里面的launch.json就是配置调试参数的位置。

launch.json

很多的配置参数，具体看参考章节的nodejs-debugging和debugging-protocol。

launch模式

launch模式就是重新打开一个浏览器实例（不是tab）。

attach模式

attach模式，是附加到现在已经打开的浏览器调试端口上，所以需要你在已经打开的浏览器中访问launch.json中配置的网站地址。

attach模式的tab窗口选择

chrome配置

windows

chrome配置远程调试端口

mac

终端执行: /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222
Linux

终端执行： google-chrome --remote-debugging-port=9222
